The typewriter illustrated in the drawings i ist-he well known Remingtonportablemachine and is designated as a'cwholeby the manera]` 10.Saidlmachine is provided with a lever 1l fixed to the rod orrock shaft12k and having attached to lits free extremitya knob l3,extendingthrough an arcuateslot 14;, located in the side plate 15 of theportable typewriter "10. :Cranky arms 16 are securede` tothe rodl2 andhave pivotallyconnected to tlie'irffreeends links 17 which in turn arepivotallyf connected to ears 18, ydependingv` from combined liftingplate` and support orfsegrnent member 19, providingfameans of to liftthe type bars 20 when the said4 lever ofh crankarm 11 is swung from theposition IssrGNoR fro REMINGTON 'rYrEwRIrnR H .moving the saidisegment`member 41.9 so as,

designated by the reference numeral 21, it' "di:

beingunderstood that4 the portable vtypewriter 10 cannotbe operated whenthe type bars 2() are lowered as designated by the ref! erence numeral'22. The member 19 and the train of mechanism for lifting and-lowering Yi the Atype system to expand the machine for use and to compact it sothat it?` maybe con` tained within its case, preferably correspond fwithf the construction4 shown in the patent to Barney No. 1,544,204,dated J une 30,1925.

"uThe carrying case element, cover or top 23 is adapted to'enclose thesides', yends and top f of the typewriter l0, and has screwed orotherwise `attached Vto it at the rear thereof a flanged member 24adapted toengage and operatea projecting member as hereinafterdescribed., Ahasp or catch 26 is pivoted "to the. front portion of thecover'orcase `part 23, said hasp being adapted to engage or cooperatewith a keeper (not shown) secured on the support or base 25; The base-25and the coverlike yelement 23 ofthe carrying Y case cooperate so `as toentirely enclose the said typewriter and when secured together permitthe machine to be carried or trans ported readily and without injury.The base 25 provides a convenient support for the macliinewhen it/"isinuse. At such times it will be understood the cover partis entirelyremoved, separated or detached from "the *i other elementor part of theoase, namely, the-base part 25. In 'order to secure the two cover partsorelements 23 and 25 together there are provided in'addition to the haspc dtional securing devices` or elements comand keeperv at the'front,additional elements thelback, which are not shown hereinbut v100 areoflwell known construction. These adprise prongsprojecting from the rearof the base and adapted to inter-lock with` recessed 4 metal fastenersfixed to the cover. The s`e` curing devices at therear and front,whereby 1thejtwo*detachable `elements of the carryingcasemaybesecuredlandlocked together,`are

he above described construction is com r gagedat'its face or'taperedside 42 withthe monto portable typewritersof the rRemington stylesuchias.' no'w.v generally. marketed and nsed. It is to` be understoodthatthe keys 127-l lcannot -be operated when Vthe type bars are in alowered position, which position is necessary in orderto place'the car-J-7 lryingicasemember yor top 23 over the. portabletypewriter-lt). vsomeinstances portable typewriters have Lbeen` rendered,V inop,er,

ative i.,ai'17`d-A `have' needed repairs due, to kthe fact V'thatpersons have 4endeavored to 'operatethe machine/without vfirst raisinglthe typebars 20 bylmeans ofthelfr'nobor finger piece13.

yAs hereinl shown invention asy related to the automatic lifting of thetype bars 20` when the abovel'mentionedf and ldescribed carrying case,top23uis removed, embodies an extendedmember er Ahead 30, provided witha pointed lextremityj31, the head or member being fixed to Voneextremity `of thel rodfor lever 32 and forming a head at the rear endyof said. lever.MA The lever or member 32is `pivoted or fulcrumed at ornear its centerltofthe block or bearing 33 ixed'to and projecting inwardfromthe o platef39. 'The movement of theextended element or lever 30 islimited by the stirruplike guide 31 .attached to` the side of the platev39, and it has xed to its free extremity a knob 34, positioned in anaperture 35, formed inthe side of the `carrying case top 23. Theconstructiony permitsthe4 disengagement ofthe extended member 30 from apm or projection 36 extending: outward from the above mentioned knob 13,when the said knob ABetis pressed oroforced inward, as

clearly shown in Fig. 5 of the accompanying drawings. When the 4fingerpiece oruknob 34 4is thus pressed inward it will render myimprovedlifting deviceinoperative when the carrying case 23 isremovedfrom the typewriter. A coiled spring 32a normally. maintains thelever member 32 in the F ig.` 3 osition with` its rear arm-,engagedwithan( arrested .by the stop and guide member 31',

A; vpiece 34 when it is pressed in. Thebell crank ,-37 is pivotally Asupported on the pin .38

,which is tixed to;and projects 'from the plate 39,. The coiled spring14() is positioned or Wound ,on the pinl `38, and -is kadapted to nnor.-mallyv hold thejbell crankagainst the stop .37, so that thecam'rshapediface 41 ofthe bell crank 371 islin" line withor provides anextensionfof the tapered-fside42 of ,theele- .,mentr30. The memberorlever32 and the partszcarried thereby',A together uwithfthe the innerface of the right-hand side wall of the case member or topg23. 'l f Theabove described construction is such as will permit the head 30,normally entheracrossthe slot`14. .The camming or forcing ofthe pinv'35andknob or iin er piece 13y by the 'cam faces y42 yand 41 `during thelifting of the cover as'described, swings the crank arm 11 and rocks'theshaft 12,

thereby swinging the crank arms 1G fromy the dotted line positionindicated at 21 in Fig. 10 to the upright position. This movement of thecrank arms raises the links 17, causing them to act on the extensions orears 18 to lift ythe type bar lifting frame or support 19 from the lowerdotted line )osition to the upper full lineposition ini" with the resultthat the machine is expanded, the type bars 20 beingelevated as showninto position to be actuated by their associate printing keys 27. Thislexpansion of the machine and lifting of the type bar sysytem isautomaticallyetfected, as will be seen. by the relative movement of thetwo parts of carrying case, that is, by the removal or, detachment of,the top,",c^over or case part 23 from the base, supporter case part 25'.The intermediate stage of the cover lifting or removal is clearly shownin Fig. 2 of the accompanying drawings. During the lifting operation itwill beV understood that the cam shaped lfacel41 of the bell crank 37will engage against'tbe stop 43, attached to'and cxtended from the plate39, this occurring during the latter part of the lifting movement orremoval of the cover. Y

As herein embodied my improved device, as related to the automaticlowering of the type bars 20, when the above mentioned and` describedcarrying case cover'23 is placedon the'said portable typewriter,embodies an engaging member 45, provided with a anged element 46, bentor forlnedlupward Vtherefromgat a right angle thereto, and providedwithl extended elements y47 havin adapted to be engaged by guide pinso1" cxtended members 49 having heads and secured to the base late; 504whichr in turn is 'screwed-or ot erwise secured rto the upper side ofthe above mentioned. base 25,' as a means of sildably attaching the saidengagimg-member orslidable plate 45 thereto. `The levers 50 areattached, at or near their 7centers, alseat 5l, to the plate'tiO.YPreferably in order to afford a loose connection of the fief 10,

The free ex-Vtremities or inner ends 53 4are positioned so as to engage With acrankpin 54, attached or fixed to about .the middle of theabovementioned rod or rock shaft 12`.` The above*` described constructioniswsuch `as Will `permit the above mentionedlflanged kmember 24 when thecarrying case cover 23 is placed overthe portable typle\vriter, toforceor slide the engaging member Which Will cause the levers A toassume the dotted line' position designated by the reference numeral" 54(F ig. 6), so as to pivot `or rotate `the crank pin54 and rock vtheshafty 12,Which Will lower the typebarsl 20."f The fplate 50 is slottedto' affordplay of said crank .pin 54. The lowerendfportion of the head30 is cut aWayas indicatediat 42l V(Figa 9)"to provide a cam' surfaceV7ivhich cooperates with the pin 36 during the replacementof the cover toforcethe head SO'jrightWard .against pressure of thespring 32, thus en`abling the lieadlto pass lover `the pin and snap leftvvard under` itwhen the cover has been brought down overthe base. Different stages ofthis operation are illustrated"`by .dotted lines in Fig. 9@

While 1 have above described the pref ferred form, constructionandarrangement of the several elements employed, it yWillbe understoodthatthe device is, nevertheless, susceptible `of considerablemodification, 4and I therefore reserve the privilege of" resortin@a toall such changes as may be "fairly embolied Within the spirit an'dscopeof the invention as claimed. l

l/Vhile it is preferred to employ the automatic type bar lifting orexpanding mechanism in combination or association with the automatictype bar compressing or compact.- ing mechanism, it Willibeunderstood'thatthe two mechanisins or sets of devices may be separatelyused if desired. i Iny othery Words', l provide means for lifting thetype bars and expanding the machine when the cover is removed ordetached from the base i e Vby Letters Patent is: i V A i Y,

' l. `Lfde'vice of the class described, ein` the type bars of a of thecarrying case, which means'y in operation are independent of the meansfor `depressing the type bars and compactingthe machine automatically"when the cover is replaced and attached to the baseer other part of thecarrying case. y e. am aware that devices have vhitherto been providedfor expanding and compact'- ing the mechanism of typewriting machines bythe relative movement 'of cover parts, but in such prior constructionthe cover parts were necessarilypermanently connected or hingedtogether, and the train of devices for actuating the expanding andcompacting mechanism, were in part on one section of the cover and inpart on the other, such' train not being disconneotible at any point.

Ingportable typewriters,` as lat present empleyechit would be highlyundesirable to have the coverrparts permanently hinged together orconnected, as this would interfere with Athe ease 4with which themachine could be operated and handled When in -Worlring conditionout ofits case. `These objectionstoprior` constructions areovercome 'by myvpresent invention, since the train of automatic expanding devices isautomatically separable, asis also the train of compacting devices, so`that the separation `or detach ment of the cover part of the case fromythe base part is in no Wise interfered with.

It Willbe seen tliatby Vmy present invention tlierea're providedautomatic means for expanding `a typewriting machine when the coverpartof its case is lifted andremoved,

saidanachine being of theexpansible and compactible type and its 4caseliavingtwo parts; that said automaticmeans comprise elements on thecover part which are entirelyI jdisconnectible both fromk theA machineitself and from the base part of the case; thativith said automaticmeans there are combined means for automatically compacting the machineVwhen the cover part is replaced; thatthe last recited automaticcoinpacting means comprise an element on the cover and an element onthebase part ofthe case, .which two elements are entirely sepa# rable ordisconnectible kWhen the two parts of the case are disconnected; thatautomatic means are vprovided for expanding the machine Wlien one partof the case is moved .relatively tothe other part, in combinationbodyingmeans of raising portable typewriter when the carrying case coveradapted to enclose thesaid portable "typewriter is removed therefrom oropened,
